SD05F-B NGK Spark Plug Caps

The NGK range of resistor covers are designed to give perfect noise
suppression across all frequencies whilst engine performance is not
adversely affected whatsoever. Some caps are none resistor such as the
LZFH & LBER. Ideal for magnetos ignition etc. Featuring a resistor
element pressed in between the plug terminal and the high tension wire
connection, the construction is extremely durable, the resistor element
is long enough to prevent interior flashover, and steady resistance is
maintained. Superlative ceramic materials are incorporated that resist
deterioration and have small resistance variation under over-load,
whilst the plug connector is made of sturdy phenolic resin, practically
oblivious to tremendous heat and high tension, and very rugged rubber
material. The heat press insertion makes the construction all the more
tough and vibration-resistance. Special rubber liners on both ends
prevent moisture from causing electrical leakage. All motorcycle
manufacturers now comply with current legislation which demands a
standard of noise suppression on every vehicle. This is achieved usually
by fitting NGK resistor covers though in many cases a combination of NGK
resistor covers and NGK resistor spark plugs (R type) is necessary to
satisfy the ministry tests. It is emphasized that despite the use of
both resistor covers and spark plugs in such engines, due to the unique
and superior construction of NGK products there is no loss of
performance or shortening of service life. LB05EMH and SD05FM being of
tough EDPM rubber construction are intended for competition/trial
applications
